While it is always possible that iOS in the Car gets delayed further into 2014, it currently seems like Apple is targeting a launch for iOS in the Car alongside iOS 7.1 next year.

As soon as iOS 8, Apple plans to further enhance its mapping and car-integration functionality. Sources say that Apple is working on an updated Maps app with indoor mapping and transit directions functionality. The company is also testing ways to integrate the iPhone’s sensors with the in-car dashboard systems.
